摘要
DG的孤岛运行可作为供电恢复过程中提高供电可靠性的一种重要运行方式.在配电网发生故障时,为了及时制定出优化的孤岛划分方案,提出了含DG的孤岛划分模型和算法,以及基于约束满足问题模型,采用回溯算法对该约束满足问题进行求解,最后用算例验证了所提方法的有效性和优越性.
DG＇s islanding is an important operation, which can improve the reliability of distribution systems in the process of service restoration. In order to form the optimization islanding scheme when a fault occurs in distribution systems, the model and algorithm based on CSP for islanding containing DGs is proposed and solved by the back-tracking algorithm. Finally, a simulation example manifests the efficiency and superiority of the proposed algorithm.
